How smart is /bant/? Help a brotha out. Factor out the X. Theres supposed to be 2 values for x in this one.

Nigger if that's right you missed one. Three degrees means three roots

Oh yeah i forgot. The problem said only the positive x-axis. Dont bother with the other one
>>
The problem is to solve the length of curve from that positive x value to the other positive x value. And i cant do that without knowing the value of the two points intersectinv the positive x axis

I don't know who gave you that function but as far as manual exercises go that's actually a pretty shitty one. You can fill these values into the original and see it ends up to zero

Do your own homework.
Don't factor out x, that work work better if you had a y value here,
Use synthetic division for a sure answer till you find enough zeros of the poly to got to a quadratic. It will be something like (x-r)(x^2-bx+c)
It doesn't look like you can do any x^2=m subsisting tricky here
Not easy stuff, what class is this? Are you sure you don't have a sign wrong?

x = the crippling realization that OP should do his own fucking Algebra II homework
>>
>>2202327
Are you supposed to find the derivative first?
>>
x^3 -3x^2 + 3
(ax^2 + bx + c)*(px+q)
x^3 * ap + x^2 * (aq + bp) + x^1 * (bq + cp) + x^0 * cq
ap = 1
cq = 3
aq + bp = -3
bq + cp = 0

a=1/p
(1/p)*q + bp = -3

b = -cp/q
(1/p)*q + (-cp/q)p = -3

c=3/q
(1/p)*q + (-(3/q)p/q)p = -3

(3p^3 - q^3) / (p*q^2) = 3

If you assume integer factors, p can be either 1 or -1 (because ap = 1). Regardless of which one you pick, it's obvious from the equation that you're not going to get any integer solutions. Conclusion: just use the closed form solution. Trying to factor it manually is not going to work.

At least you plugged it into something less common.

Thanks for the help anon but the test was like 5 hrs ago. I couldnt leave it alone so i had to look for answers even after the test. I dunno the teacher usually gives us doable problems. That one was unexpected

Fuck u capitalist pig im looking for manually answering it by hand and apparently its not possible i had to use a calculator.

But it is possible to solve by hand

Just not by manually trying to factor it.

But x^3=0 has only one solution.
>>
>>2202327
0=x^3-3x^2+3
0=3x^2-6x
X=(6+-√(-6)^2-4×3×0):2
X=(6+-6):2
X=0 or x=6
